11 Claims.

This invention relates to improvements in corded fabric which is adapted to be made as a tape having a corded edge for mounting slideasteriers or the like thereon.

@ne object or" this invention is to provide an improved corded iabric which is adapted to be made as a tape for mounting slide-fasteners or the like thereon, in which the cord is Woven in with the :body ci the tape at the time of manufacture of the tape.

Another object of this invention is to provide an improved corded fabric which is adapted to he made as a tape for the mounting of slideiasteners thereon, in which the tape is characterized by superior strength and ilexibility.

With the above and other objects in View, as will appear to those skilled in the art from the present disclosure, this invention includes all ieatures in the said disclosure which are novel over the prior art.

In the description and claims, the various parts and steps are identified by specific terms for convenience, but they are intended to be as generic in their application as the prior art will permit.

ln the accompanying drawing forming part of the present disclosure7 in which certain ways of carrying out the invention are shown for illustrative purposes:

Fig. 1 is a iront elevation or face view of a piece of corded tape made in accordance with the present invention, and illustrated as having slideiastener elements mounted thereon;

2 is a schematic enlarged View similar to Fig. i. of the area 2 of Fig. l;

3 is a transverse sectional view taken on line 3 3 of Fig. 2;

Fig. 4 is a longitudinal sectional view taken on line li-il of Fig. 3;

Fig. 5 is a view similar to Fig. 3 of a modified construction;

Fig. 6 is a view similar to Fig. 5 of still another modiiied construction; and

4ig. 7 is a transverse sectional View on line l--l of Fig. l.

Referring to Figs. 1 to 4 of the drawing showing the particular form of the invention chosen for illustration therein, the corded tape I Il includes a relatively-thin tape-body II formed of longitudinal warp strands I2 interwoven with transverse weft strands or picks I3, and includes a relatively-thick twisted cord I4 formed of a plurality of twisted cord-strands I5, I6, I'I and I8, with the weft strands I3 Woven transversely between certain of the twisted cord-strands, as shown.

In making the particular tape IE! illustrated in Figs. 1 to 4 inclusive, the cord-strands I5, I6, I'I and i3 are given one-quarter of a com-plete twist for every four picks I3, although it will be appre- 5 ciated that a greater or less number of picks per quarter-twist could be employed. Thus, by observing Fig. 2 of the drawing, it will loe seen that four picks are illustrated as passing beneath the cord-strands I8 and l1, and the next four pick-s pass beneath the cord-strands I5 and I8, and so on. Four weit picks pass transversely between the four cord-strands with two cordstrands above and two below each pick. The angie of passage of the portions oi the picks that extend between the cord-strands, varies in successive picks of any group of four picks, in accordance with the stresses which are present as the result of the twisting of the cord-strands, as will .be evident from a consideration of Figs. 3 and 4 of the drawing The different cord-strands I5, I5, Il and i8 are marked with different surface-indications on Figs. 2 and 4, so that the eye can readily follow the continuity ci the various strands throughout their extent.

The two warp strands i9 and 2l) to the right of the twisted cord Ill, serve as anchor-strands for the weft picks or strands I3.

In the form of the invention illustrated in Fig. 5, the tape-.body I l is formed of interwoven warp strands l2 and weit strands E3, the same as for the form of the invention illustrated in Figs. 1 to 4 inclusive, but in this figure the anchor warp strand 29 is omitted so that there is only the one anchor' warp strand I9 to the right of the twisted cord i4 which latter is formed of the cord-strands lli, It, Il and i8.

In the modiiied form of the invention illustrated in Fig. 6, the tape-body Ii is formed of interwoven warp strands I2 and weft strands i3. the same as heretofore shown and described for the forros of the invention previously illustrated, but instead of using only four cord-strands to form the twisted cord, ve strands 2l, 22, 23, 24 and are employed to form a twisted cord 26, and the wei t strands I 3 are anchored without ernploying any anchor warp strands to the right of the cord 26, by being passed around rst one, then around the next, of the successive cord- *lstrands 2l, 23, 2 and 25, as the twist imparted 50 t0 these strands successively brings iirst one and then another to the position of strand 2| shown in Fig. 6.

Fig, 7 and Fig. 1 illustrate the manner in which the usual form of slide-fastener elements 21 are 55 fastened along the corded edge of the tape.

Instead of having four picks for each quartertwist of the cord-strands, there could be more picks or less picks per quarter-twist if desired. Instead of having the cord made of four cordstrands, it could be made of more cord-strands or less cord-strand, but it is preferable to have an even number of cord-strands in the forms oi the invention illustrated in Figs. 1 to 5 inclusive, in order to have an equal number of cord-strands on the opposite sides of the picks passing through the cord. For similar reasons, it is preferable to employ an odd number of cord-strands in the form of the invention illustrated in Fig. 6. For simplicity of illustration, the tape-body has been shown in the drawing as made of a simple basket weave, but it will be appreciated that any desired form of weave can be employed.

Corded tape made according to this invention has greater strength and flexibility than corded tape as heretofore made by sewing cord on previously woven tape. Also the cord will not pull cil? of my improved tape. can be made more cheaply, and as it is made complete before dyeing, there are no coloror shadematching troubles.

The invention may be carried out in other specie ways than those herein set forth without departing from the spirit and essential characteristics of the invention, and the present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
